Article Synopsis
- Ferroptosis is a newly discovered form of iron-dependent cell death important for plant health and mutualistic relationships between microbes and hosts.
- Endophyte Streptomyces hygroscopicus OsiSh-2 induces moderate ferroptotic cell death in rice plants, which is crucial for optimal plant growth and establishing beneficial interactions.
- This process also enhances rice's defense mechanisms, improving resistance against diseases like rice blast, highlighting potential strategies for increasing crop yields.
Article Synopsis
- Endophytes significantly influence plant growth and immunity, but their disease resistance mechanisms are not fully understood.
- The study identified ShAM1, an α-mannosidase from the endophyte Streptomyces hygroscopicus OsiSh-2, which enhances resistance against the rice pathogen Magnaporthe oryzae by triggering immune responses through the jasmonic acid-ethylene signaling pathway.
- ShAM1's ability to release oligosaccharides from rice cell walls supports its role in activating plant defense mechanisms and suggests potential for using endophyte metabolites in managing plant diseases.
Objectives: Isolation and identification of a novel laccase (namely Lac4) with various industrial applications potentials from an endophytical bacterium.
Results: Endophyte Sd-1 cultured in rice straw showed intra- and extra-cellular laccase activities. Genomic analysis of Sd-1 identified four putative laccases, Lac1 to Lac4.
